如何在iOS中的电子邮件的HTML主体中嵌入图像 [英] How to embed an image in the HTML body of an email in iOS

问题描述

我正在尝试将图像包含在从iPad发送的HTML电子邮件的正文中。看起来不可能我试图使用CID方法，但似乎在iOS中，不可能获取/设置附件的CID。

I'm trying to include an image in the body of an HTML email sent from an iPad. It seems impossible. I have tried to use the CID approach, but it seems that in iOS it is not possible to get/set the CID of attachments.

我也试图嵌入图像与 src =data：image / png; base64，blahblahblah。当您撰写邮件时，似乎可以正常工作，但收到邮件后不会显示。

I've also tried to embed the image with src="data:image/png;base64, blahblahblah". When you compose the mail it seems to work, but nothing appears when the mail is received.

任何想法？

更多细节：
我们不是在电子邮件底部附加JPEG / PNG的解决方案。这很容易与 [composer addAttachmentData：mimeType：fileName：] 。

我们正在寻找在HTML格式的电子邮件中嵌入图片 inline 的解决方案。您可以围绕该IMG标签包装链接，以便收件人点击IMG时，他/她将被链接到应用程序的iTunes页面。

We are looking for a solution where the image is embedded inline in an HTML-formatted email. You could wrap a link around that IMG tag, so that when the recipient clicks the IMG, he/she will be linked out to the app's iTunes page.

推荐答案

从 github

Download the NSData+base64 category from github.

然后执行以下操作：

NSData *imageData = [NSData dataWithContentsOfFile:pathInDocumentDirectory(imagePath)];
NSString *base64String = [imageData base64EncodedString];
NSString *imageString = [NSString stringWithFormat:@"data:image/png;base64,%@", base64String];

最后，将 imageString 身体，你想要这个图像出现。

Finally, put the imageString in the HTML body where you want this image to appear.
